Inventor: SMITH ROBERT PAUL
IPC: F16L3/217
Filed: 1984-10-19
Abstract: A shock arrestor comprises a cylinder 12, a piston 14 slidably mounted in the cylinder and which divides the cylinder into respective fluid chambers 20, 22, passage means 27, 28, 31, 32, 33, 37 being provided through which fluid may flow in one direction between the chambers regardless of the direction of piston movement. Flow control means 30 (shown in detail in Fig. 4) is provided to restrict the flow of fluid through the passage means, to restrain movement of an article to which the shock arrestor is connected. The flow control means comprises a pressure responsive spool valve 72 located within a valve chamber, located within the piston rod 16a of the shock arrestor, the spool valve being operative to permit flow between the chambers at relatively low flow rates; but at least significantly to restrict such flow when the flow rate becomes excessive, the apertures 77a and 78a moving out of alignment. Notwithstanding the restriction of flow in such circumstances, means is provided to permit at least limited flow between the chambers, to accommodate for thermal expansion or contraction. A member 71 forming the housing for the spool valve 72 moves off its seat 103 against the bias of spring 101 to open a creep passage 104.

Title: Traffic system comprising steerable vehicles adapted for use as tracked vehicles and track-defining roads
Inventor: MEHREN HERBERT
IPC: B62D1/26
Filed: 1985-02-01
Abstract: A system for transversely guidable vehicles comprises supporting arms 7, 8 and guide rollers 9, 10 which are mounted on these arms and which, when projecting sideways in the track lane 3, cooperate with guide surfaces 11, 14 bordering the road side. Since the transverse guidance arrangement on the driver's side is exposed to considerably less danger of being damaged than the arrangement on the right-hand side which is remote from the driver, only the right-hand guide roller needs to have a retractable design. A rigidly mounted left-hand guide roller 9 is advantageous when filtering into a track section. First, with the rigidly mounted guide roller 9 on the driver's side, the vehicle is driven up to the left-hand guide edge 11, which is extended forward on one side, and is guided on one side along this edge until the beginning of the right-hand guide edge 14 when the steering is turned, for example. By virtue of being guided on one side, the vehicle is in a specified transverse position before entering the track where it is guided on both sides, and therefore a road sensor 17 attached to the underside of the vehicle for extending the right-hand transverse guiding arrangement is operated reliably by a ramp-shaped control cam 13 on the road surface without special attention being required by the driver to adjust the guide rollers 9, 10. At the end of the track section 3 the transverse guiding arrangement is automatically retracted in an appropriate manner. <IMAGE>

Abstract: A method of achieving pairwise key variable (or base key) exchange between groups of participants with mutual authentication. The method uses Shamir's secret sharing method combined with the trapdoor features of exponentiation/logarithmisation modulo a suitable large prime, as used in the Diffie-Hellman secret number exchange method. The method preserves the secrecy of the numbers held by the participants of the shared secret, whilst at the same time permitting them to transmit information over a public medium, which, when issued by sufficient of the participants, enables the participants to mutually authenticate one another, and key variables to be exchanged pairwise between them.
Patent GB-2179679-A (GB)
Title: Forming a dielectric film and semiconductor device including said film
Inventor: KAGANOWICZ GRZEGORZ
IPC: H01L29/51
Filed: 1986-08-26
Abstract: Silicon (44) is oxidized in an oxygen-containing ambient to form a first region (48) of silicon oxide. Once oxidation has begun, reactive sputtering of aluminum in an oxygen plasma is initiated. This forms a second region (50) of said dielectric film which comprises a mixture of silicon and aluminum oxides. A third region (52) comprising substantially aluminum oxide is formed by the continuing reactive sputtering step. In making a MOSFET device, for instance, a metal electrode layer (54) may be deposited over the third region (52), and source and drain regions (56, 58) may be formed in the silicon (44) provided as a layer formed on a substrate (42) such as of glass. A semiconductor device comprising said three region dielectric film interposed between an electrode and a semiconductor body has little or no shift in threshold voltage, providing good stability, and can be fabricated in substantially less time and/or at lower temperatures than prior art methods. <IMAGE>
